Extending Object-Oriented Approaches to Hydrological Modelling based on Triangular Irregular Networks

Abstract

This research project aims to further explore an object oriented methodology in which a hydrological system is considered to be a series of interacting hydrological elements. It will extend Slingsby’s hydrological model TINMOD (2002) whose data structure is based on a TIN with embedded methods and behaviours to build, maintain and derive its topology – as well as derive hydrological information (flow-paths, basins, flow length) about itself. Specifically, this project aims to add functionality to TINMOD that allows it to derive unit hydrographs for mountainous environments where infiltration and interception rates are minimal.
